To all whomit ma/y concern:

Be it known that I, EMIL-.WAGENER, a subject ofthe Emperor of Germany, resid ingat Dahlhausenfon-the-Ruhr, Westphalia, Kingdom of Prussia, Germany, have inh vented a certain 'newand 'useful Improvement in Regenerative CokefOvens, of which the following 1s a true and exact description, reference beingl had to the accompanying drawings, whic form a part thereof.

1y present .invention rrelates to regenerative colte ovens, and `the yobject of the inven- 4'tion to provide an arrangement of heating gas; supply connections, whereby iames and hotproducts of combus- -tionare caused to ow through the heating fines, first ,in one direction and then reversely, as the regenerator connections are adjusted, Without reversal or alteration in the How of the gas which is burned.

Av further object of the invention is to provide an arrangement whereby the hot air 3,5; ybe embodied.

y taken transversely to t with 4from the regenerator may be supplemented by warm air from passages in 'the oven '.structure. The various lfeatures of novelty which characterize the` invention are pointed out Yarticularity in the claims annexed to and orming a. part of' this specification. For a betterunderstanding ofthe invention, however, and the. advantages possessed by `l it, referenceshould be had to the accompanymg drawings .and descriptive matter, in which I havev illustrated and described one 'of the' forms in which the invention 'may 'Of the drawings: Fi ure 1 is a section e ovens, the left handl pdrtion bein teken on. the line A B and the right hanportion ontlie 'line (d D- ofy Fig. t2.' Fi 2 is a longitudinal section taken along tgeline Ek F of Fig; l1, vand Fig isa horizontal sectiontnkenalqngtlie line of Fig. 2. Inthe construction shown by the draw# 13 rare formed 'underneath the oven chambers 20. lIn the wall between each adjacent palr of oven chambers'are formed vertical` eating ues arranged in groups, each groupconsisting of a yflue 3 communicating with the upper end' o at its lowerend with a sole channel 2'; a riiue 10 communicatinr at its uppei'end iiaflue 3, a fine l1 communicatlng at its lower` end with the ylower'v end of flue 10;: and a flue 12 pipes and communicating at its up er end with vthe upper end of fiue 11, an at its lower end wlth a sole assage or channel 13. The regenerators, tie construction of which is not Shown by the drawings, but which may be of usual form, are connected, one to each sole channel 2 by passages 1 at the left hand side of the structure as seen in Fig. 2 and the other by assages 14 tofthe right hand ends of the so e` channels 13.

With the 4direction of thedraft of the heating gases as shownin the'figures, the hotair of combustion enters from the left regenwater-which can be regulated separately -for each lwall-through the channels l into heating groupithrough' its flue 3.' The heat ing gas`1s supplied to the heating-lines from abovethlpughfan upper main pipe 4, gas nozzles 6 and from below through a lower main pipe 7, as'pipes8 and nozzles 9 and the quantlty can ge regulate aty each nozzle. The hot air from the fines 3 is mixed at the upper turning point with the heating gas from the nozzles 6. The burning gas descends with a surplus of air in the flues 10. At the lower turning point the gas from nozzles 9 takes up its air of combustion, or at least a part of same, from the passage ways or tunnels beneaththe retorts through the channels into which the nozzles 9 extend` The heating gas rising in the fines 11 i receives at the next upper turning point some more gas ,from burner pipes 6 and travels through flues 12 sole channels 13 and lues l14, to the. regenerator at the right, where it delivers its heat to the checkerworln In addition tothe groups rof flues referred to, there are two other lues 15, in the Wall at the side of each oven, one at each end. The

lthe, solefehannels 2 and rises for each two lower burner pipes 9 at the ends heat the two end flues 15, the air supporting corn- ,bustion therein'being supplied through the channel at the lower end of the flue's into which their nozzles 9 extend. -The gas tiow through he lues 15 is continuously in the same direction, the gases from the fines 15 passing out ofthe lues 15 at. their upper ends into the upper ends of the adjacent fines 3.

eriod withfone rection of the draft. the atter is reversed by turning the. usual valves, or like draft shifting devices. rlhe hot air then enters from the regenerator on the right through lues 14 into the channels 13 and After operatingtfor the usual or desired I from there passes into the wall flucs 12.1

shown 1n the drawing. The heating gases pass through the lines 1l, 10, 3, sole chanuchv 2 and fines l to the regenerator at the lelt and all the gas burners continue burnlng as Having now described my invent-ion, what I claim as new and desire to secure by Letters Patent, is:

1. In a regenerative coke oven structure, the combination with theretorts, of s'ole channels Beneath the retorts, vertical heating fines at the side of each retort 'arranged in groups in which adjacent iues are connected togetheralternately 'at top and bottoni, with the end ues of each group 'connected at. their lower ends, one to `one and the other to another oi said sole channels, whereby each of said; flue groups forms a continuously open channel between a pair of said sole channels, regenerative connections to said sole channels whereby the iow of air f through said sole channels and the groups of flues connecting thorn may be reversed, contlnuo'usly operating gas burners arrangedat the tops of said end flues of each group and at the lower end of each of the tivo flues of each group adjacent the end fines thereof;

2. ln a regenerative coke oven structure, the combination with the rotor-lsI of solo channels heneath the reto'rts, vertical heating lues at the side of each retort arranged in groups in which adjacent fines are connected together alternately at top and bottoln, with the end lines of each group connected at their lower ends, one to one and the other to another of said sole channels, whereby each et said iue groups forms a continuously open 'channel between a pair of said sole channels, regenerative connections whereby lthe HDW of air through said sole channels ,and the groups of lues connecting* them may he reversed, continuously operating gas burners opening into the passage formed by each group of connected fines at a distance from the ends thereof, and air supply channels in the oven structure opening-into ysaid Vpassages at distances from their ends throuvh which atmospheric air may pass into sai passages-r' 4 EMIL VVAGENER.
